Comparison of English and American coins:
For scale information: the UK Penny coin used on most of the photos is just slightly larger than a US Cent coin. The actual diameter is 3/4 inch or 2 cm. The silver 20p coin is very slightly larger than the one penny coin-the one penny coin will fit inside the points of the 20p coin. A Euro 5 cent coin is approximately the same size as the 20p coin.
